AIR-COOLING SYSTEM FOR INTERNAL-COMBUSTION ENGINES.

Application filed November 16, 1911.

To all whom it may concern:

Be it known that I, JOHN WILKINSON, of Syracuse, in the countyofOnondaga and State of New York, have invented a new and usefulAir-Cooling System for Internal- Combustion Engines, of which thefollowing is a specification.

This-invention has for its object the production of a particularlysimple and" efiicient air cooling system for the internal combustionengines of motor vehicles; and it consists in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure l is a transverse sectional view of a portion of a vehicleembodying my inven tion, parts of the engine being omitted. Fig. 2 is atransverse sectional view of the casing for the engine, contiguous partsof the frame of the vehicle being also shown. Fig. 3 is an inverted planof the hood. Fi 4 is a detail view. of the arch around t e upper portionof the fan. Fig. 5 is a fragmentary view of the hood, looking forwardly,illustrating one of the depending flanges carried by the hood.

1 are the sills; 2 designates the dash board, and 3 the engine of amotor vehicle, the engine comprising a plurality of cylinders 4 arrangedone behind the other or tandem, and having lengthwise flanges 5.

6 is the crank shaft of the engine.

This air cooling system for internal combustion engines comprises,generally, a casing inclosing the engine, such casing including aremovable hood and means dividing the casing into upper and lowercompartments, and means as a fan for circulating the air through thecasing.

7 is the removable hood which normally rests at the lower edges of itsside walls on the sills 1, and which is pivoted at 8 near its front endto the sills land is movable.

ends thereof, and being secured at their spaces betweenthe side edges ofthe wall 11 and the side walls of the hood are closed by flanges orwings 12 carried by the hood and extending downwardly from thefrontedges of the wings or partition sections. The partition section 10is formed with passages through which the. cylinders 4 project, andpreferably these passages are confined by cylindrical shells 13supported in openings in the partition 10 and surrounding the flangedportions of the cylinders.

.14 is a boot, or pan, constituting the bottom and portions of the sidewalls of the casing. The boot, or pan, is closedat its front end by theupright wall 11 which is provided with an axialbpening 16 through whichextends a bearing 17 for the crank shaft 6. The boot or pan 14 issuitably supported by thesills 1 and is here shown assecured thereto inany suitable manner as by bolts 18 engaging with the horizontal flangesof angle irons 19 secured to the inner faces of the sills 1.

The hood is usually provided with a screened air inlet opening 20 at itsfront end and also'such front end overhangs the front wall 11, and isopen at 21 for permitting the inlet of air, and a deflector 22 islocated below the opening 21 for directing the air upwardly through suchopening 21. Additional side deflectors, as the deflector 23, are alsoprovided between the sills and in front, of the deflector 22. v

The means for circulating the air through the casing is here shown as aperipherally discharging suction fan 24 mounted-on the rear end of thecrank shaft 6, the upper portion of such fan running close to an arch25carried by the dash board 2 of the vehicle, and the lower portion ofthe fan running within an extension 26 of the boot or pan 14. Said arch25 is provided with flanges 27- at its ends, which depend between thesills 1 and meet the upper ends of a semi-annular flange 28 within therear end of the boot or. pan 14. The parts 25 and 28 form an outletopening for the casing through which the air-is drawn by the fan 24located in the rear of said opening.

The fan 2% is here shown as'containing a suitable disk clutch 29 and auniversal joint. 3Ov through which power is transmitted to the drivingwheels of the vehicle.

In operation the air is drawn through the openings 20 and 21 to theportion of the hood above the partition sections-9 and 10 and is drawndownwardly through the passages 13 into the boot or. pan 14k andisdischarged through the rear end pf the pan 14 The air is preventedfrom entering below the partition sections 9 and 10 by the front walllland the Wings 12.

This air cooling system is particularly advantageous in that upon theremoval of the hood, portions of the casingare removed therewith so thatparts andappurtenances of the engine within the boot or pan or below thepartitions 9 and 10, are easily accessible.
